Let's see what the impact of HF19 was. Let's compare statistics between approximately 1 month of data before HF19 and approximately 1 month since HF19. The "PRE-HF19" data is from between May 23rd and June 20th. The "POST-HF19" data is from between June 20th and July 18th.

Account growth
We've seen the amount of accounts increase by 40.55%, this is likely mostly unrelated to HF19. It's impossible to know how much user growth that is, because users can have multiple accounts.
Reward pool
The rewards have dropped 28.32%. This is mostly because of the drop of the STEEM price. But what's much more significant is that self-voting has increased by 130.16% after HF19! This is something to be concerned about in my opinion as more and more people become aware that you can make more money by voting on your own low value comments than voting on top quality content.
Posts
No significant changes.
Comments
Comment rewards relative to the total reward pool have increased by 32.54%. The amount of the comment rewards that were assigned by self-votes has increased by 40.52%. It's obvious that since HF19 there is a rather significant rise in the amount of rewards people put on comments!
Impact of max voting weight increase (from 0.5% to 2%)
The number of votes per account has dropped only 28.02% of the maximum potential of 300%. This means that many curators have used the slider to decrease voting weight below 100%. This also means that posts are curated by less people. It's highly preferred to let users curate as much content as possible, so this is a negative result.
Author income
The average monthly author income has decreased by 62.04% (average post reward by 59.38%). This is because of the drop in STEEM price and the increase in authors. There were 79.56% more authors active this month which made almost exactly the same amount of posts per author as the month before. Assuming an identical amount of posts per author, to increase the income of the average author, the STEEM price had to rise by more than 79.56%.
